To all whom timely concern.

State of New Jersey, have invented new and useful Improvements inSiphon-Heads,

of which the following is a specification.

This invention relates to improvements in siphon heads wherein aspring lield valve operates in a cavity formed in the head proper and coacts with a valve seat provided at the upper end of said cavity. 1

The problem which presents thegreatest difliculty in siphon head construction is to provide a simple and practical siphon head which combinesthe advantagcs,(1) of be,-

ing absolutely sanitary, (2) of not'being particularly liable to breakage or derangement, and (3) ofefficiently and reliably preventing the escape of the highly volatile carbonic acid gas with which thewater is charged. This problem is satisfactorily dealt with by certain priorconstructions, as examples of which may be mentioned, the constructions shown in my prior U. S. Patent No. 1,040,226of Oct. 1, 1912, in my pending U. S. application, Serial No. 801,224, and in the pending application of William P. Dilts, Serial No. 827,389.

In the three prior constructions referred to, the valve organizations have certain common characteristic features, viz., the formation of the valve stem of a metal bar for the purpose of strength, the covering of the metal bar with a sleeve of hard non-corrosive material for the purpose of sani-, tation, the provision of a non-corrosive valve head at the lower end of said sleeve,

the said valve head having a yieldable;

engaging surface, and the provision of a relatively hard valve seat for cooperation with the engaging surface of the valve head. While the valve organization as just explained is practical and satisfactory for the principal purposes in view, it is, as carried out in the prior constructions identified,

open to objection, in that its assemblage is Y somewhat difficult, requiring particular care and skill and taking'iup, in the aggregate, for the daily output of an average plant, a substantial amount of time.

The present invention which relates to the general type of construction, exemplified in the three prior constructions above identified, is concerned especially with the organi- V zation of the valve and its immediate ap-- ,Be it knownthat 1, CHARLES DE LUKA CsE-j vros, a citizen of the United States, resid ing at Nutley, the county of Essex and purtenances its object is to provide a valve organization which while serving the advantages above stated inthe same measure shownby way of example in the accompanying drawings, in which:

designate parts throughout the several The construction shown in Fig. 1 is generally similar to the construction shown in my said pending application and in common withthe latter includes a head 1, preferably of porcelain, having its lower end in the onrrcn.

form of an enlarged socket 2, which fits over the bottle neck 3 and is held in position, for example, by securing rings 4 and 5; a bellshapedor generally globular cavity 7 opening "from the inner end of the socket 2; a liquid passage 8 extending upwardly from the cavity 7 and having the usual liquid dis charge duct 9; a bell-shapedv member 10 of hard or relatively hard non-porous material, such as rubber, having a circumscribing flange 11 to engage over the mouth, of the bottle,said member 10 providing a cavity, internal to the cavity 7 and communicating at one end with the liquid passage .8 andat its other end with the siphon tube 6; a hard rubber sleeve 13 carrying the siphon tube 6 and threaded in a depending flange 12 formed as a part of the member 10; a gasket 14 arranged between the member 10 and the bottle neck; and a gasket 15 arranged f between the member and the cavity The foregoing elements being old, need no description other than the mere enumeration thereof above given.

The member 10 carrles within its internal cavity a seat 16 for a valve 17 and, while this valve and its seat are similar as regards relation to the valve and valve seat shownin my said pending application, they are substantially different as regards their structure. The elements of the valve are a metal core 18 which has a roughened or corrugated sur face and a fork-like enlargement 19 at its lower end; and a hard non-porous and noncorrosive sleeve 20, preferably composed of rubber which'is cast upon the core 18 and completely incloses the same except for a short projecting portion at theupper end of I said core. The sleeve 20 terminates at its 20 lower end in an enlarged relatively hard valve head 21 which is reinforced by the enlargement 19 and is suitably formed to efliciently' discharge thefunctions of a siphon head valve. The head 21 is complete, in itself, as the valve and the engaging valve surface is in fact the surface of. said head, such valve surface having a conical outline, and uniformly engaging the conical inner circumferential face of the'valve seat- 16 substantially throughout the area of said seat. The sleeve 20 and the head 21 integral therewith being cast upon the stem 18, take a secure grip upon the surface corrugations of said stem, I r In the construction shown in my said pending applicatiom'the seat for the valve is formed as an integral part of the member 10. In the present construction, the valve seat consists of a ring of soft rubber castwithin' the cavity of the member 10 at the upper end thereof. a i

The valve'is' operated by a spring held button 22 which, in the way in whichitis secured to; the projecting or uncovered upper end portion. ofthe stem 18 and in allother respects is similar to the construction shown in my saidjpending application. I

Fig. 8 shows the'f'eatures of the present invention in connection with the construction shown in the said pending application of VVilliamP. Dilts, Serial No. 827,389. In this'case,'the siphon head 25 is composed of compressed material, such foryexample, as that used for electrical insulation and known under the various trade names of bake: lite,- condensite and hi-heet. The siphon' is held upon the bottle neck in/the qopies of this patent #188 be obtained for usual manner and is providedwith an internallythreaded valve chamber 26 in the lower portion of which is fittedasleeve 27 carrying the siphon tube 6. Thevalve and its stem are of the construction already described herein and the valve head cooperates of the core 18. In both cases, the surface of the core is corrugated and is securely gripped by the sleeve and'valve head cast 7 thereon.

The valve herein described may be manufactured. with facility, the only operation involved, being that of casting'the hard nonporous and non-corrosive envelop or sleeve and the valve head integral therewith upon the metal core. The relatively soft valve seat may be "readily cast in the cavity provided therefor and efficiently cooperates.

with the hard valve head in preventing the escape of gas. o v i. i

Having fully described my invention, I claim: r

In combination, a siphon head having means for attachment upon the bottle neck and having a cavity adapted to aline with said neck, anda liquid duct extending upwardly from said cavity, a valve organization comprising a core, and a valvehead of hard non-porous and non-corrosive material cast upon the lower end of said core and having a conical seating face, an elastic valveseat secured in said cavity for cooperation with said valve head and having a conical valve engaging face, and means for holding said valve normally against said seat, the valve head engaging with its hard outer surface directly against said seat substantially throughout the area of the conical face thereof.

Intestimony whereof I have'hereunto set my hand in presence of two subscribing witnesses.
